Transparent background for figures

I get the following warning in r2011a
set(gcf, 'Color', 'None')
Warning: Setting the ColorSpec to 'none' for a figure will not be allowed in a future release.
I use the "none" color so that I can print pdf and eps files with transparent backgrounds. How are you supposed to set a transparent background?

You can edit the eps file generated by print, and remove the line which creates the background rectangle, thus making the background transparent.
Or you can use the latest version of export_fig, which will do this for you when the -transparent option is specified, and will allow you to export to pdf as well.

Digging in the source of print I've found the colornone command in 2011b. It has a help section, but is not included in the local or net docs.
But the warning appears also. The print command simply disables the warning:
This does not look very trustworthy.

What do you mean transparent? Do you mean white background color? Would the pdf or eps file come out the same as set(gcf,'Color','None') as set(gcf,'Color',[1 1 1])?
I used to use whitebg(). But it's not really white background anymore since the default color is [.8 .8 .8]. whitebg() just turns it to [.3 .3 .3]. Same is the function colordef(). I

In the figure window, select property inspector by double clicking on your plot. There is a box styling section in which you can select the background color, by selecting none you can have it transparent. If you want this setting already in your code, you can select "Generate Code" in the file tab of the figure window and have all your manual settings in code.

You can use the exportgraphics command, which was introduced in R2020a, to easily generate output with a transparent background if the output format supports it. For example, the following code will export the plot to a PDF file with background transparency.
If you also want the background of the axes (the area behind the lines on the plot) to also be transparent in the exported file, set the axes color to 'none':
set(gca, 'color', 'none');
Another benefit of using exportgraphics is that the generated output is closely cropped around the exported content, eliminating excess "white space" around the plot.
